Aims: To evaluate breast self examination (BSE) practice and the effect of a training program conducted by healthcare professionals on BSE. Materials and Methods: Women were randomized into control and test groups with both groups completing a questionnaire and three independent interviews where their BSE practices were evaluated. Results: In all, 39.5% of the participants were previously provided information on BSE by healthcare professionals while 25.8% had no knowledge of BSE prior to enrollment. Compared to those informed about BSE through other means such as television, radio, and the internet, the scores of the first, second, and third visits were higher (p<0.05) in individuals who received BSE education from healthcare professionals and hospitals. Conclusions: BSE training provided by healthcare professionals may increase early breast cancer diagnosis and treatment rates by improving BSE awareness and practice.

As society proceeds rapidly toward a knowledge-oriented stage, knowledge as an intangible asset has gained increasing importance. Companies increase their competitiveness and generate extra value through continuous investments in the management of intellectual property (IP). Thus, the prime concerns of companies have been protection of their technological innovation output through filing for IP rights, and maximization of their interests through utilization of intangible assets. Despite the importance of technological innovation in the management of a company, few studies have analyzed the key factors in the management of IP and activities for technological innovation. This study aims to derive policy implications for managing IP and effective capacity building for technological innovation. For this purpose, the author has employed empirical tests to identify the major factors influencing the direction of technological innovations in a company.

The importance of Information technology (IT) has been growing. Thus, it is critical for firms to choose the optimal information technology development mode in order to ensure that maximum benefit is derived from IT. Despite its importance, however, there is little comprehensive research on choosing the IT development mode that firms undertake. To fill this gap, this study attempts to propose a parsimonious as well as comprehensive IT development framework based on strategic value and the uniqueness of IT resources. In addition, this study analyzes the impact of the fit between the theoretically proposed IT development mode and the actually used mode on the performance of Korean firms. This study contributes to and expands the literature on IT development modes by considering various development modes in real time. Moreover, the results serve as a stepping stone for managers who want to develop or adopt IT effectively.

With wide recognition of significant roles of venture companies in economic and industrial developments, substantial academic attention has been paid to understanding venture success and numerous policy measures have been made to help them. A serious problem, however, is that only a few limited number of venture could successfully grow to be large firm. The goal of this paper is to identify critical factors to drive 'leapfrogging' growth of venture companies by analyzing the success cases in Daejeon area. The theoretical analysis and case study suggest 1) founders' entrepreneurship continuity as a significant internal organization factor for growth and highlight importance of 2) exploring foreign markets and globalization of business operation in the early stage of growth. Furthermore, the research results identify two critical innovation strategies, 3) ambidextrous R&D strategy and 4) open innovation strategy, for entrepreneurial founders to effectively catch the business chances brought by environment change.

The purpose of this paper is to study the pattern of interactive learning in strategic networks. Interactive learning is defined as the exchange and sharing of knowledge resources conducive to innovation between an innovator firm, its suppliers, and/or its customers. The strength of internal knowledge resources can either hamper or facilitate levels of interactive learning. We assume that more complex innovative activities urge firms to co-ordinate and exchange information between users and producers, which implies a higher level of interactive learning. To test our theoretical claims, we estimated the level of interactive learning of firms in strategic networks with: (1) their customers, (2) their suppliers. Theses analyses allow a comparison of the antecedents of interactive learning of firms participating in strategic networks. Our findings suggest that interactive learning with customers is positively affected by company's capabilities and value-created activities, and with supplies is positively affected by value-created activities and technology innovation centers.

A classic document clustering technique may incorrectly classify documents into different clusters when documents that should belong to the same cluster do not have any shared terms. Recently, to overcome this problem, internal and external knowledge-based approaches have been used for text document clustering. However, the clustering results of these approaches are influenced by the inherent structure and the topical composition of the documents. Further, the organization of knowledge into an ontology is expensive. In this paper, we propose a new enhanced text document clustering method using non-negative matrix factorization (NMF) and WordNet. The semantic terms extracted as cluster labels by NMF can represent the inherent structure of a document cluster well. The proposed method can also improve the quality of document clustering that uses cluster labels and term weights based on term mutual information of WordNet. The experimental results demonstrate that the proposed method achieves better performance than the other text clustering methods.

This paper examines the intra-and inter-regional linkages of public research institutes (PRIs) with various innovation actors in Korea. In spite of the general consensus on the role of PRIs as innovation facilitators as well as creators, the attributes of regional spillover effect of knowledge created by PRIs have not been understood completely. Some argue that PRIs play pivotal role in encouraging intra-regional innovation networks through collective learning process. Others argue that PRIs are not necessarily related to intra-regional knowledge transfer, but play more important role in establishing national and international innovation linkages. This study attempts to figure out the current status of innovation linkages of Korean PRIs and to prove how the internal and external attributes of PRIs influence the development of spatial innovation linkages. Furthermore, it also tries to draw policy implication from empirical analysis results.

Neuro-fuzzy systems are multi-layered connectionist networks that realize the elements and functions of traditional fuzzy logic control/decision systems. A trained neuro-fuzzy system is isomorphic to a fuzzy logic system, and fuzzy IF-THEN rule knowledge can be explicitly extracted from the network. This talk presents a brief introduction to self-adaptive neuro-fuzzy systems and addresses some recent research results and applications. Most of the existing neuro-fuzzy systems exhibit several major drawbacks that lead to performance degradation. These drawbacks are the curse of dimensionality (i.e., fuzzy rule explosion), inability to re-structure their internal nodes in a changing environment, and their lack of ability to extract knowledge from a given set of training data. This talk focuses on our investigation of network architectures, self-adaptation algorithms, and efficient learning algorithms that will enable existing neuro-fuzzy systems to self-adapt themselves in an unstructured and uncertain environment.

This study aimed to measure consumer information competency, which indicates consumers' general ability to search and utilize information. The model of this study was constructed in order to identify how consumer information competency influences the efficiency and the effectiveness of external information search. The model was verified with related prior knowledge as a moderator variable in order to understand holistic consumer information search activity. The result of the study is as follows. First, the concept of consumer information competency was constructed with four sub-abilities: define, search, extract, and synthesis & use. The ability of define was the highest, as opposed to the ability of extract, which was the lowest. Second, consumer information competency was lower for women as well as for low family income. The sub-abilities of search and synthesis & use were lower for aging consumers. Third, consumer information competency has positive effects on information search efficiency and effectiveness. Moreover, the efficiency influences the effectiveness positively. Fourth, prior knowledge moderates the effect of consumer information competency to the efficiency. Only for consumers with high knowledge the efficiency has the effect of mediating between consumer information competency and the effectiveness.
